MACHINE FOR SHAPING PIECES DOUGH.

Application led June 14, 1928, Serial No. 285,329, and in Switzerland April 17, 1928.

The subject matter of the present invention is a machine for shaping pieces of dough having a travelling endless shaping band and at least one shaping table turnable about a vertical axis for shaping pieces of dough placed between band and table. The distance between band and table is adjustable.

A plurality of tables may be arranged below a single band and the tables may be brought one after the other into the operative position below the band by a turning motion about a vertical axle common to all the tables.

A constructional example of the subject matter of the present invention is illustrated on the accompanying drawings, in which- Fig. 1 is a front elevation with one of the tables shown in section,

Fig. ln shows in elevation a detail of the driving mechanism,

Fig. 2 is a horizontal section along line II*II in Fig. 1,

Fig. 3 is a side elevation of the machine,

Fig. 4 shows a detail in elevation, and

Fig. 5 is a vertical section of the detail of Fig. 4.

Referring to Figs. 1-3, ldenotes a standard on which three horizontal arms 2, 3, 4 arranged as a spider are turnably mounted and at the end of each arm a vertical bearing 5 is provided. In the smooth bores of the bearings 5 axles 6 are mounted, which carry at their upperl ends disks 7, 8 and 9 provided with plates or tables 10 made, for instance, of wood. At the lower end of each axle 6 a hand wheel l1 is arranged which serves to turn or oscillate the table 10 during the shaping operation. On a gudgeon 16 fixed in the standard 1 the upper part 17 of the machine is carried, having at its top an electric motor 18. On the shaft 19 of the latter a pinion 20 is fixed which meshes with a larger toothed wheel 21. On the axle of the latter a chain wheel 22 is fixed cooperating by means of a chain with the chain wheel 23. The latter is mounted on a shaft 24 carrying at one end a` pinion 25. The pinion 25 meshes with a gear wheel 26 (Figs. l and la) which in its turn cooperates with a gear wheel 27. In the shaft 24 a bush 28 (Fig. 2) is mounted with which a lever arm 29 is integral, the latter being pivotally connected to a lever arm 30 loosely mounted on the shaft 31 on which the gear Wheel 27 is fixed. This manner of mounting the gear wheels 25, 26 and 27 ensures a driving connection for any vertical adjustment of the band. On the shaft 31 two chain wheels 32 are fixed over which! endless chains 33 run. The latter cooperate with similar chain wheels 34 fixed to a shaft 35 arranged parallel to the shaft 31. The distance between thebearings 36 and 37 of the shafts31 and 35 may be adjusted for tlghtening the chains 33 by means of spindles provided with screw thread 39. In the outer sides of the chains 33 angular parts 40 (Figs. 4 and 5) are provided to which' wooden bars 41 are fixed which serve as members for shaping pieces of dough.

The shaping band formed by the wooden slabs 41 with its shafts and chain wheels is mounted in a frame 42 having a pin 43 point-- ing in the upward direction and provided with circumferential grooves. A gear wheel 44 cooperating with said grooves may be turned by means of a crank 45, whereby the distance between the shaping band andthe table 10 may be adjusted at will.

By turning the spiderframe 2, 3, 4 about the gudgeon 16 the tables 10 may be brought one after the other into the position below the shaping band. In this manner on one table the piece of dough to be shaped may be placed, whilst on the second -table which is below the band the piece of dough is being acted upon and shaped in a known manner, the table being simultaneously turned or oscillated by means of the hand wheel, andfrom the third table the finished shaped product can be removed. Thus a practically uninterrupted shaping action is obtained.

By a suitable turning to and fro of the hand-wheel 11 cylindrical dough pieces or pieces shaped as loaves or balls may be obtained. The arrangement of a plurality of tables cooperating with one shaping band ensures a continuous Work of the machine.V

I claim:

1. A machine for shaping pieces of dough, comprising in combination, an endless shaping band, means for driving said band, at least one shaping table turnable about a vertical axle, and means whereby the distance between said band and said table may be regulated.

2. A machine for shaping pieces of dough, comprising in combination, an endless shaping band, means for driving said band, a

plurality of shaping tables turnable about vertical axles, said axles being mounted 1n a device turnable about a vertical axle to llO bring one table afterthe other into the operative position below the band, and means to adjust the distance between said band and said tables.

3. A machine for shaping pieces of dough, comprising in combination, an endless shaping band, means for driving said band, a plurality of shaping tables turnable about vertical axles, said axles being mounted in a device turnable about a vertical axle to bring one table after the other into the operative position below the band, and means to displace the band in the vertical direction for adjusting the distance between said band and said tables.

4. A machine for shaping pieces of dough, comprising in combination, an endless shaping band, means for driving said band, a standard in which said band and said driving means are mounted, a pluralityT of shaping tables turnable about vertical axles, al

spider in which said axles are mounted and which is rotatably mounted about a vertical axle in said standard for bringing one table after the other into the operative position below the band, and means to displace the band in the vertical direction for adjusting the distance between said band and said tables.

5. A machine for shaping pieces of dough, comprising in combination, an endless shaping band comprising two endless chains running over chain wheels and arranged parallel to each other and wooden slabs pivot-y ally connected to and transversely arranged to said chains, means for driving said band, a plurality of shaping tables turnable about vertical axles, said axles being mounted in a device turnable about a vertical axle to bring one table after the other into the operative position below the band, and means to adjust the distance between said band and said tables.

6. Avmachine for shaping pieces of dough, comprising in combination, an endless shaping band comprising two endless chains,

running over chain wheels and arranged parallel to each other and vwooden slabs pivotally connected to and tranversely arranged to said chains, means for driving said band, a standard in which said band and said driving means are mounted, a plurality of shaping tables turnable about vertical axles7 a spider in which said axles are mounted and which is rotatably mounted about a vertical axle in said standard for bringing one table after the other into the operative position below the band, and means to displace the band in the vertical direction for adjusting the distance between said band a-nd said tables.

7 A machine for shaping pieces of dough, comprising in combination, an endless shaping band comprising two endless chains running over chain wheels and arranged parallel to each other and wooden slabs pivotally connected to and transversely arranged to said chains, means for driving said band, said means including an electric motor, a train of gear wheels interposed between said motor and said chain wheels of the band, two of said gear wheels being mounted in levers pivotally connected to each other and both meshing with a third gear wheel turnable about the axis of said pivot to permit a vertical displacement of said band relatively to said motor in which the driving connection is maintained, a standard in whichsaid band and said driving means are mounted, a plurality of shaping tables turnable about vertical axles, a spider in which said axles are mounted and which is rotat-V ably mounted abouty a vertical axle in said standard for bringing one table after the other into the operative position below the band, and means to displace the band in the vertical direction for adjusting the distance between said band and said tables.

In testimony whereof I have signed my name to this speciication.
